Simplifies a funnel path using linecasting.

Running time is roughly O(n^2 log n) in the worst case (where n = end-start) Actually it depends on how the graph looks, so in theory the actual upper limit on the worst case running time is O(n*m log n) (where n = end-start and m = nodes in the graph) but O(n^2 log n) is a much more realistic worst case limit.

Requires graph to implement IRaycastableGraph
